<p>
          I have been attempting to understand the differences between compilers
          and environments when running tests on Boost Phoenix.
        </p>
<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem">
              Some environments are limited in the memory available for testing and
              I have broken some large tests into smaller pieces.
            </li>
<li class="listitem">
              Some of the problems experienced in testing are specific to particular
              compilers being used.
            </li>
<li class="listitem">
              Some problems have occurred with several more recent compilers.
            </li>
<li class="listitem">
              One problem is that I do not have access to all of the compilers used
              in the tests or by users.

<li class="listitem">
              The most difficult problems to diagnose have been some which occur
              when the compilation uses optimization.
              <div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: circle; ">
<li class="listitem">
                    Some of the boost tests use optimization but most do not.
                  </li>
<li class="listitem">
                    It is not usually documented which tests are optimized.
                  </li>
<li class="listitem">
                    This means that a lot of tests run there which fail when optimized.
                  </li>
<li class="listitem">
                    This has made the identification of the cause of the problems
                    more difficult.
